Letitia Grenier is director of the PPIC Water Policy Center, where she is also a senior fellow. She previously directed the Resilient Landscapes Program of the San Francisco Estuary Institute, where she served as a resource for local and national media; advised government and agency staff; and worked with partners to conserve California’s living resources by developing landscape-scale, collaborative, science-based visions and solutions. She was also the 2020 PPIC CalTrout Ecosystem Fellow and an adjunct fellow with the PPIC Water Policy Center. Throughout her career, she has worked as a proponent and leader of science-based management. In 2019 and 2015, she served as the science lead for the State of the Estuary Report, and she was also the science lead for the 2015 update to the Baylands Ecosystem Habitat Goals, heading a team of over 200 environmental scientists, managers, and regulators to develop recommendations for restoring and maintaining the health of the Bay’s tidal wetlands in the face of rising sea levels and other stressors. She completed her PhD at University of California, Berkeley, where her research concentrated on the ecology of the Bay-Delta estuary system.
